A technique that strengthens concrete by stretching steel cables through it after the concrete hardens.
A method of reinforcing concrete by tensioning high-strength steel tendons after the concrete has been placed and gained sufficient strength. Post-tensioning reduces cracking, deflection, and the volume of concrete required by placing the concrete in compression. It is widely used in parking structures, bridges, elevated slabs, and long-span floors.
Post-tensioning allows the 9-inch parking structure slab to span 60 feet without intermediate beams.
